Product details

The Pentair 474972 is the manifold kit for the MasterTemp 125 pool and spa heater. It brings together the parts on the water side of the heater that wear or leak: the coil and tubesheet sealing o-ring kit, the bottom plate, the baffle plate, the bypass valve, the water pressure switch, a 5/16 in. stainless steel washer and the hex cap screw.

Why a kit

Opening the manifold on a MasterTemp is most of the labor, whichever part failed. A weep at the tubesheet means new o-rings, a heater that short cycles or will not fire may be the pressure switch, and a sticking bypass valve throws off water flow through the exchanger. Having all of them in the box means the manifold goes back together once.

Before you order

This kit fits the MasterTemp 125 only; the 175 through 400 models use a different manifold. Check the rating plate on your heater and match the model before ordering.

Questions and answers

What people ask about this product, answered by our pool techs.

Which heater does this fit?
The Pentair MasterTemp model 125 only. The larger MasterTemp sizes use a different manifold, so check the rating plate on your heater.
What comes in the kit?
The coil and tubesheet sealing o-ring kit, the bottom plate, the baffle plate, the bypass valve, the water pressure switch, a 5/16 in. stainless steel washer and a hex cap screw.
Do I need it if the manifold is only leaking?
A leak at the manifold is usually the tubesheet o-rings, which are in this kit. Since the kit also brings a new bypass valve and pressure switch, many techs replace the whole set while the manifold is apart rather than opening it twice.
Is the manifold body itself included?
The kit supplies the plates, valve, switch, seals and hardware listed. Compare the list against what your heater needs before ordering.
